BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Calibrachoa plant, botanically known as Calibrachoa sp. and hereinafter referred to by the name ‘INCALCOWHI’.

The new Calibrachoa plant is a product of a planned breeding program conducted by the Inventor in Johannesburg, South Africa. The objective of the breeding program is to create new compact, mounding and early-flowering Calibrachoa plants with large attractive flowers and good garden performance.

The new Calibrachoa plant originated from a cross-pollination conducted by the Inventor in Johannesburg, South Africa in November, 2015 of a proprietary selection of Calibrachoa Llave & Lex. identified as code number Ca14-5199-2, not patented, as the female, or seed, parent with a proprietary selection of Calibrachoa sp. identified as code number Ca14-5231-6, not patented, as the male, or pollen, parent. The new Calibrachoa plant was discovered and first selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Johannesburg, South Africa in April, 2017.

Asexual reproduction of the new Calibrachoa plant by vegetative terminal cuttings in a controlled greenhouse environment in Gensingen, Germany since April, 2017 has shown that the unique features of this new Calibrachoa plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Calibrachoa have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘INCALCOWHI’. These characteristics in combination distinguish ‘INCALCOWHI’ as a new and distinct Calibrachoa plant:

-   -   1. Compact and uniformly low mounding to eventually trailing         plant habit.     -   2. Moderately vigorous growth habit.     -   3. Freely branching habit; dense and bushy appearance.     -   4. Early and freely flowering habit.     -   5. Large white-colored flowers.     -   6. Good garden performance.

The new Calibrachoa plant can be compared to plants of the female parent selection. Plants of the new Calibrachoa differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Calibrachoa are more compact than plants of         the female parent selection.     -   2. Plants of the new Calibrachoa flower earlier than plants of         the female parent selection.

The new Calibrachoa plant can be compared to plants of the male parent selection. Plants of the new Calibrachoa differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Calibrachoa are more compact than plants of         the male parent selection.     -   2. Plants of the new Calibrachoa flower earlier than plants of         the male parent selection.

Plants of the new Calibrachoa can be compared to plants of the Calibrachoa x hybrida ‘Balcal14141’, disclosed in U.S. Plant Pat. No. 30,200. In side-by-side comparisons, plants of the new Calibrachoa differ primarily from plants of ‘Balcal14141’ in the following characteristics:

-   -   1. Plants of the new Calibrachoa are more compact than and not         as vigorous as plants of ‘Balcal14141’.     -   2. Plants of the new Calibrachoa have larger flowers than plants         of ‘Balcal14141’.

Plants of the new Calibrachoa can also be compared to plants of the Calibrachoa spp. ‘SAKCAL108’, disclosed in U.S. Plant Pat. No. 24,484. In side-by-side comparisons, plants of the new Calibrachoa differ primarily from plants of ‘SAKCAL108’ in the following characteristics:

-   -   1. Plants of the new Calibrachoa are larger than plants of         ‘SAKCAL108’.     -   2. Plants of the new Calibrachoa have larger flowers than plants         of ‘SAKCAL108’.     -   3. Flowers of plants of the new Calibrachoa are whiter than         flowers of plants of ‘SAKCAL108’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Calibrachoa plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Calibrachoa plant. At the top of the photographic sheet is a side perspective view of a typical flowering plant of ‘INCALCOWHI’ grown in a container and at the bottom of the photographic sheet is a close-up view of a typical flowering plant of ‘INCALCOWHI’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the spring in 15.25-cm containers in a polyethylene-covered greenhouse in St. Thomas, Ontario, Canada and under cultural practices typical of commercial Calibrachoa production. During the production of the plants, day temperatures averaged 27° C. and night temperatures averaged 15° C. Plants were pinched three weeks after planting and were ten weeks from planting rooted cuttings when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
